Abstract
A method and apparatus for coding an image including calculation of motion vectors of vertices of a patch in an image being encoded and providing an output of horizontal and vertical components of the motion vectors of the vertices and information specifying that values of the horizontal and vertical components of a motion vector for each pixel in the patch are integral multiples of 1/d of a distance between adjacent pixels, where d is an integer not less than 2.
